gabrielblack··on The first two hours of MTV (1981) [video]
I only remember that in the video the band played during a basketball match and I have a vague memory of the music. I think that the group disappeared after the first album. Thank you for the advise, I'll take a look to Reddit, too !
gabrielblack··on The first two hours of MTV (1981) [video]
Does exist DB, list or equivalent with all the titles of every video transmitted by MTV ordered by year ? I'm desperately looking for a video transmitted continuously in 2001, 2002 or 2003 by MTV in Europe that has a special meaning for me.
gabrielblack··on Laser pulse travels 300 times faster than light (2002)
IMHO, just another blatant article claiming revolutionary discovery without details, papers, peer reviews aka clickbait. Moreover, this is an article you expect to find in generalist press, not in a supposed scientific journal. It's an article without signature also contradictory in some points, it starts with: "Despite exceeding the vacuum speed of light, the experiment is not at odds with Einstein's theory of relativity and is explainable by existing physical theory" and it ends with " however, because it is still correct to say that information cannot be transmitted faster than the vacuum speed of light". Is this the kind of journalism we like ?
gabrielblack··on SpaceX Dragon ISS Docking Autopilot PID Controller in JavaScript
IMHO the title is misleading : it's a simulator of ISS Autopilot not the real one.

gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
Some conspiracy theorist freak want transform a legitimate scientific paper in some kind of proof of alien technology existance, maybe ! :-)
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
And WIFI is total bullshit. They say "WIFI frequency" aka 2.4 GHZ because, as we all know, that is the deregulated frequency reserved for consumer application. So, IMHO the researcher shouldn't have used that term, is confusing ! From there to say that the experiment involve the problem of powering cordless devices in the sense of electronic gadget with an access point is a complete misunderstanding of the sense of that research. They intend to power something very close to the emitter in medical/niche applications with a dedicated emitter. This is an important clarification because WIFI data transmission delivered power is NOT constant and too weak, differently from the one from a signal generator near the device.
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
Simply I don't like fake news.
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
The administrators changed the title of this article for a reason. Moreover, that device is intended to be installed very close to the "consumer", that is useful in medical application, for example, where is no advisable to install the battery in a device to be implanted in the body. So you can install the emitter , transmitter, whatever you want call it on the skin. And WIFI is total bullshit. The say "WIFI frequency" aka 2.4 GHZ because as we all known is the deregulated frequency reserved for consumer application. So, IMHO the researcher shouldn't have used that term, is confusing ! From there to say that the experiment involve the problem of powering cordless devices in the sense of electronic gadget is complete misunderstanding of the sense of that research. Man , science is not an opinion.

Exactly, moreover they speak about WIFI band, but in the experiment they didn't use an Access Point but a signal generator with the test device at * 2.5cm (0.9 inch) * from the antenna, if I've understood: "For the energy harvesting, we used the 2.45 GHz resonant patch antenna with a return loss of more than −35 dB at 2.45 GHz and a gain of 7 dBi. The antenna is fed by the signal generator at 0 dBm. The antenna is placed at ~2.5 cm away from the MTJ array". Let's try to measure at 2.5 meters. That is a laboratory experiment not intended to prove that you can give power to something moving around. They speak about neuromorphic computing: I know there are devices implanted int the brain of blind people receiving power from a radio device installed very not inside the cranium but at the outside, on the skin. That kind of application is more credible.
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
The title of this article was changed, by the administrators I guess, I think it's good in times where someone think opinions are more relevant then science.
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
Yeah, exactly the point I was try to explain being bullied for.
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
errata corrige: ... that is not and will not be possible.
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
I wrote it fast, I rewrote it. My point is that the title is misleading and suggest you can use WIFI radiation as power source to do something useful in the near future in consumer electronics. You simply will not.
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
I think titles that are clickbaits should be avoided, titles like "eternal youth found" referring to article with: "eating apple seeds for 10 years you can gain up to 10 microsenconds lifespan".
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
the title is misleading , you should specify microwatt
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
Show me applications in microwatt range to justify the "usable", moreover you need a wifi. Why someone should use that instead of a solar cell, like the one on calculators ?
gabrielblack··on Spin-torque oscillators for WiFi band transmission and energy harvesting
If someone reading the post here is thinking that will be possible give power to "small devices" using WIFI, that is not and will not be impossible. We are talking about few micro amperes when a coin cell battery can deliver 220.000 micro amperes, as paragon. There are some niche applications in micro ampere range, but in that cases there are some reliable and more stable solution, like cesium batteries. Dave of EEVBlog has a mission, debunk this wireless energy affirmation, explaining why it's simply impossible, for example: https://www.youtube.com/watch?v=P8s3Xjeg0sk

Moreover the power is related to the distance to the wifi source and the presence of an active WIFI obviously doing this kind of solution at least impractical even for ultra low power consumption applications. An Apple tag uses a coin battery and I think will use that solution for a veeeeery long time.

gabrielblack··on Piano teacher gets copyright claim for Beethoven’s Moonlight Sonata [video]
I can't understand why Youtube has no procedure to flag companies as "Wicca Moonlight” like scammer / troll so, after a certain number of infractions like that one ( pretending to be the rightful owner of the rights on BEETHOVEN music !), they are sanctioned in some way or banned. That to add some symmetry to the procedure to fight trolls trying to steal other peoples hard job.
gabrielblack··on Scientists Believe US Embassy and CIA Officers Hit with High-Power Microwaves
What about misused or defective radio equipment ? I guess that they have powerful microwave sat equipment, in there. This is a more reasonable explanation then mysterious "death ray" that, anyway, should be detectable and traceable with the right equipment, in case someone want to prove its existence. Moreover, what's the logic in creating a gratuitous diplomatic incident and possibly cause reprisals against the responsible ? IMHO , this story is the perfect click bait so nobody want to consider more logic and simple explanations.
gabrielblack··on WSL2 corrupting Git repositories and shell history
I experienced this problem and a ext4 corruption, too. Because my company force me to use Windows for internal policy, my previous solution was a VMware VM , accessed "remotely" by my IDE. Then I wanted try the new sauce. My colleagues working to legacy code on SVN also experienced problems (anyone else ?). So I switched back to VMWare VM. The other considerations were that a VM can be easily backupped copying a directory and, if I need to change computer or an additional environment, the migration of the whole environment is extremely easy. Moreover i use snapshots, so if something goes wrong at OS level I can go back with a click.

gabrielblack··on Rocky Linux: Community enterprise OS compatible with RHEL
I was reading this post about the reasons of that: " Many of us have deployed CentOS servers to production environments, trusting Red Hat’s promise that CentOS 8 would be supported through 2029. The Red Hat announcement means that those installs reach end of life after less than 2 years, with the only upgrade path being Centos Stream — AKA being a forced beta tester for RHEL".

gabrielblack··on 'Machine-gun with AI' used to kill Iran scientist
> a machine-gun mounted on the Nissan pick-up was "equipped with an intelligent satellite system which zoomed in on martyr Fakhrizadeh"

Less or more the technique seen in the '97 remake of "The Day of the Jackal" https://en.wikipedia.org/wiki/The_Jackal_(1997_film) with Bruce Willis: https://www.youtube.com/watch?v=TJ4j7OArO8Q , without depleted uranium ammo

gabrielblack··on Former Israeli space security chief says aliens exist, humanity not ready
Anyone with actual proofs, I think. We have to filter the source according to the type of information: a political tabloid isn't a good source of information for science, even if someone post it on HN. An accredited scientific journal is a good source. Furthermore, it's necessary looking for "red flags" in our source (critical reading): if the source has few verifiable facts or no verifiable fact at all, maybe it's a case of "alternative fact" (aka bullshit). The search for alien life is taken seriously by the scientific community and a researcher has all the motivations to be part of the history proving the existence of extraterrestrial intelligence. If you ask me, I am "probabilist", I think that they could be out there. I'm waiting for evidences. This article is not.
gabrielblack··on Former Israeli space security chief says aliens exist, humanity not ready
Exactly: that remind me Kary Mullis, a Nobel Prize (https://en.wikipedia.org/wiki/Kary_Mullis#Use_of_hallucinoge...). I had a colleague AIDS denialist, he told be that AIDS doesn't exist and that's a fact because Mullins sayd so. So I read about this man that is a brilliant biochemist but with no title or specialization or experience to qualify him as AIDS expert. Reading about his personal life, I learned he was also an hallucinogens addict.About that, he also claimed "to have been rescued from a fatal accident by a person travelling in an astral plane, and to have conversed with an alien disguised as a raccoon" (https://www.telegraph.co.uk/obituaries/2019/08/19/kary-mulli...). So I asked to my colleague: "what's your opinion about aliens?", his response: "they are among us, I'm sure: Mullins sayd so!". :-)

And don't forget. this isn't the original article: it's an article describing another article. What's that ? Metajournalism ?
gabrielblack··on Former Israeli space security chief says aliens exist, humanity not ready
No photos, no references: could be a man with the same name. And he's 87 years old, I'm sorry but he can be senile, without evidences, this article IMHO is only a clickbait example.
gabrielblack··on Former Israeli space security chief says aliens exist, humanity not ready
No photo, no references, no curriculum ! Could be a person with the same name! This article is full of speculations, Could someone honestly say that there is a single thing reliable there ? IMHO it's more like the plot of an episode of "Men In black" then a serious newspaper article.
